IS 1570 (Part 2/Sec 1) 15C8 vs BS 970 (Part 1) 045M10
Strong Match — 87.7% match
based on chemical composition and mechanical property overlap.
IS 1570 (Part 2/Sec 1) 15C8 (IS 1570 (Part 2/Sec 1):1979) and BS 970 (Part 1) 045M10 (BS 970 (Part 1):1983) are both steel grades.
Both fall under the Carbon Steel category.
IS 1570 (Part 2/Sec 1) 15C8 is typically used for boiler billets, bars and sections, welded round link chains, billets and bars for forgings, carbon steel forgings and case hardened parts (the standard links this grade to is 2100, is 6967, is 1875, is 2004, is 4432), while BS 970 (Part 1) 045M10 is commonly used for case hardening steel for mechanical and allied engineering purposes (table 11 mechanical properties)..
IS 1570 (Part 2/Sec 1) 15C8 is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 1) 045M10 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, IS 1570 (Part 2/Sec 1) 15C8 vs BS 970 (Part 1) 045M10 is a 87.7% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a strong match overall at 87.7%.
Frequently Compared With IS 1570 (Part 2/Sec 1) 15C8:
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
